“The picture shows Dietrich Buxtehude playing a viol, Johann Adam Reinken at the harpsichord, and an unidentified person singing (possibly Johann Philipp Förtsch, singer and composer at the Hamburg opera). Johann Theile definitely is not pictured on this painting – the recent discovery of a portrait of Theile from a contemporary music print shows a different person. The singer in the painting has often been erroneously identified as Buxtehude.”
